Note: Experiment 2 (Voice-Feedback) is identical to the first experiment (in which there was no vocal protest, but mere pounding on the wall) except that vocal protests were introduced. The complaints could be clearly heard by the teacher. Experiment 3 (Proximity) placed the learner in the same room as the teacher, a few feet away. Experiment 4 required the teacher to place the learner's hand upon a shock plate in order to administer the punishment.
